Times have certainly changed. A few years ago, it would have been considered an anomaly for a German car manufacturer to officially unveil a key production model at an auto show in China. However, today, Porsche did just that when it showed off their new Panamera super sedan at the 2009 Auto Shanghai. China has huge market potential for all auto manufacturers and this proves it. The Porsche Panamera will be available starting in the fall with a V8 engine available in either 400 hp or 500 hp with rear-wheel and all-wheel drive options.
